I'm slightly skeptical about how genuine this giveaway is due to the lack of information surrounding it and the lack of effort put into the Gleam page. Anyway, if you have a minute to spare and are ok with the risk of this being fake, you could enter this giveaway with the following prize list:
1st Prize: Playstation Vita
2nd Prize: an iPod
3rd Prize: A Speaker
That's as detailed as the prize list gets. There doesn't appear to be any information about which iPod or what type of speaker could be won.
This giveaway ends in just three days and can be entered using the link below. Personally I think it's worth entering just in case it is genuine because winning a Playstation Vita or an iPod would definitely be great.
